(Phys.org) —The universe may have existed forever, according to a new model that applies quantum correction terms to complement Einstein's theory of general relativity. The model may also account for dark ...

(Phys.org)—The laws of thermodynamics are best known for dealing with energy in the context of physics, but a new study suggests the same concepts could help improve economic growth models by accounting ...

Even if you live more than 1,000 miles from the nearest large city, it could be affecting your weather. In a new study that shows the extent to which human activities are influencing the atmosphere, scientists ...

(PhysOrg.com) -- One of the biggest goals of the LHC is to discover the Higgs boson, the only particle in the Standard Model that has not yet been observed. In general, physicists are pretty confident that ...

Today the Linear Collider Collaboration published its Technical Design Report [PDF] for the International Linear Collider (ILC) - a proposed 31-kilometer electron-positron collider that will both complement and advance beyond the physics of the Large Had ...

In 2030, if all energy is converted to clean energy, humans will consume about eleven-and-a-half terawatts of power every year, all sources combined. If there is to be a clean-energy economy based on renewable ...

(PhysOrg.com) -- Intensive research around the world has focused on improving the performance of solar photovoltaic cells and bringing down their cost. But very little attention has been paid to the best ways ...

(PhysOrg.com) -- By suggesting that mass, time, and length can be converted into one another as the universe evolves, Wun-Yi Shu has proposed a new class of cosmological models that may fit observations of the universe better ...

(Phys.org) —Blazars are the brightest of active galactic nuclei, and many emit very high-energy gamma rays. New observations of the blazar known as PKS 1424+240 show that it is the most distant known source ...

(PhysOrg.com) -- "In many ways, the standard model of cosmology works very well," Jose Cembranos tells PhysOrg. "However, there are very basic features that we just do not know. We have dark energy and dark matter. They d ...

(PhysOrg.com) -- Like all galaxies, our Milky Way is home to a strange substance called dark matter. Dark matter is invisible, betraying its presence only through its gravitational pull. Without dark matter ...

(PhysOrg.com) -- An alternative proposal to dark energy in which the Earth sits near the center of a large void is undergoing scrutiny, and the results show that void models fit poorly with observed data. ...
